APPARATUS FOR SCOURING, BLEACHING, DYEING OR OTHER SIMILAR OPERATIONS 0N TEXTILE MATERIALS Filed July 23, 1947 Patented July 3, 1951 APPARATUS FOR SCOURING, BLEACHING,

DYEING, OR OTHER SIMILAR OPERA- TIONS N TEXTILE MATERIALS Jean Rottier, Barcelona, Spain Application July 23, 1947, Serial No. 763,100 In Spain March 31, 1942 Section 1, Public Law 690, August 8, 1946 Patent expires March 31, 1962 3 Claims.

The invention relates to textile finishing and especiallythe operations of scouring, bleaching, dyeing, etc., which are effected by submerging the textiles properly prepared into vessels or tubs which contain the appropriate liquid for the treatment. The textile or other material to be treated is ordinarily suspended from bars or crossbars which rest on the edges of the vessel, and which are ordinarily moved by hand and intermittently by the laborer, in order that all the points of the material become equally impregnated with the liquid that constitutes the bath, and so that the action of said bath is uniform throughout the textile or other material. This movement up to the present has been effected by hand, such operation requiring the constant attention of more than one laborer.

By means of the improved apparatus which is the object of this patent it is attained that the material will have within the bath a periodical alternating movement, this movement being obtained by mechanical means and in a completely automatic manner.

The improvements consist, essentially, in arranging the bars which support the textile piece upper end of rods or stems which may slide vertically guided by appropriate bearings fixed on the walls of the tub, the opposite end of these stems resting, each one, on an oscillating lever, the movement of which is produced by means of an eccentric operated by a motor or any other means. With this arrangement the oscillating movement of the levers, acting on the sliding rods, will cause the elevation of the frame up to a certain degree, then its descent and so on successively, moving the textile or material in the bath.

In the attached drawing there is shown, as an example, one form of execution of the present invention, the figure being a perspective view of a vessel or tub provided with the mechanism for executing automatically the motion of the material.

In the drawing, II] shows the vessel or tub of cement, wood or any other appropriate material, which contains the bath for bleaching, dyeing, etc., adequate for the treatment to which it is desired to subject the textile. On the upper edge of tub III rests a rigid frame H, which carries a series of cross-bars I2, from which are suspended the plaits of the textile I3, by means of strings I4.

The mechanism for the operation of the frame is constituted mainly by the levers I5 and I6, pivoting around the axle I'I, fixed on the wall of the tub by means of the bracket I8. The arms I6, of these levers, extend beyond one end of the tub and may be joined to form a single central arm I9, thereby forming a fork of large size supported on both sides of the tub by the axles I'I.

At the end of the lever arm I5, there is formed a small platform 20, on which rests a vertically displaceable rod 2 I, guided by the brackets 22 and 23, attached to the walls of the tub. The rod 2|, in its upper part terminates in a platform 01' plate 25, which extends over the edge of the tub and underneath the frame, so that the frame rests on its central part at both sides, on the. platforms 25.

The common extension or arm I9, of the fork formed by the levers terminates preferably in a roller 26, which is in contact with an eccentric wheel 21, fixed on the axle 28, which itself turns on the bearings 0r supports 29. The axle 28 is so driven as to produce a slow oscillation of the levers and this drive may be obtained, for example, by means of a toothed wheel 30 and screw 3|, and the latter is driven by a motor 32.

With the purpose of compensating partly for the weight of the frame itself and of the textile under treatment counterweights 35, variable in number, can be placed on the front end of the levers or joining point of the fork of the same.

The operation of the arrangement is as follows:

When the axle 28 turns the eccentric wheel 2'! acts on the roller 26 at the end of the arm I9 common to both levers, and, the latter, oscillating around the axles II, push upwards the rods 2|, which elevate the frame to a certain point raising with it the cloth suspended from the cross-bars. Upon stopping the motion of the eccentric wheel 21, the weight of the frame and of the cloth cause them to descend slowly so that the latter becomes completely submerged in the liquid without being subjected to any tension nor rubbing which otherwise might produce stains or unevenness in the pieces subject to treatment.

The arrangement of the moving upper frame that holds the cross-bars, and which simply rests on the edge of the tub or on the organs transmitting to it the ascending or descending movements, makes it possible to withdraw the whole set of frame, cross-bars and textile, by means of any kind of lifting apparatus and to transfer it to another tub for the purpose of subjecting the fabric either to Washing or to other baths which simplifies to a large extent the operations followed at present.

I claim:

1. An apparatus for scouring, bleaching, dyeing and similar operations, comprising a liquid containing tank having an opening, a frame having dimensions corresponding to said opening supported on the edges thereof, a series of parallel bars supported on said frame for supporting the textile pieces to be treated, guiding brackets fixed to the walls of said tank, vertically extending stems sliding in said brackets, platforms at the upper ends of said stems extending over the edges of the tank and under said frame, said frame resting on said platforms on opposite sides, and means for moving said stems upwardly carrying the frame with said pieces and then permitting said frame to descend by gravity.

2. In an apparatus as set forth in claim 1, said means for moving said stems comprising a double armed lever, the arms thereof, partially surrounding said tank, axles placed at both sides of said tank, on which said lever is fulcrumed, said lever contacting the lower ends of said vertical stems, and an eccentric wheel rotated at suitable speed contacting the end of said lever remote from said vertical stems.

3. In an apparatus as set forth in claim 2 wherein counterweights are provided cooperating with an arm of said lever to balance the weight of the textile pieces.
